Once upon a time, in the cold, blue ocean, a  whale shark and a killer whale became friends. The whale shark was gray with white spots and was 59 feet long. The killer whale was black with a white eye patch and tummy and was 27 feet long. Both had to eat a lot because they were so big. Whale sharks eat tiny plankton, but killer whales eat big, juicy salmon. The whale  shark invited the killer whale to dinner but the killer whale didn't eat  because she doesn't eat plankton. She was hungry so she said, "Come to my house and eat with me". So they both swam to the killer whale's house. But whale sharks don't eat salmon, so the whale shark didn't eat, and he was hungry. They decided they could not be friends because they didn't eat  the same thing. So the two friends cried. But eventually, they decided  to have a potluck dinner so they could each bring along their own dish. Then the whale shark could eat plankton, and the killer whale could eat salmon.

You can be friends with someone who is different if you think about what they like.
